NAME

CHI::Driver::Memcached -- Distributed cache via memcached (memory cache daemon)

VERSION

version 0.16

SYNOPSIS

            

              
              
use CHI;
my $cache = CHI->new(
    driver => 'Memcached',   # or 'Memcached::Fast', or 'Memcached::libmemcached'
    namespace => 'products',
    servers => [ "10.0.0.15:11211", "10.0.0.15:11212", "/var/sock/memcached",
    "10.0.0.17:11211", [ "10.0.0.17:11211", 3 ] ],
    debug => 0,
    compress_threshold => 10_000,
);
            
          

DESCRIPTION

A CHI driver that uses Cache::Memcached to store data in the specified memcached server(s).

CHI::Driver::Memcached::Fast and CHI::Driver::Memcached::libmemcached are also available as part of this distribution. They work with other Memcached clients and support a similar feature set. Documentation for all three modules is presented below.

CONSTRUCTOR OPTIONS

Namespace, appended with ":", is passed along to the Cached::Memcached::* constructor, along with any constructor options not recognized by CHI - for example servers, compress_threshold and debug.

If you need more control over the options passed to Cache::Memcached::*, you may specify a hash directly in memd_params.

METHODS

Besides the standard CHI methods:

memd

Returns a handle to the underlying Cache::Memcached::* object. You can use this to call memcached-specific methods that are not supported by the general API, e.g.

            

              
              
$self->memd->incr("key");
my $stats = $self->memd->stats();
            
          

UNSUPPORTED METHODS

These standard CHI methods cannot currently be supported by memcached, chiefly because there is no way to get a list of stored keys.

dump_as_hash

clear

get_keys

get_namespaces

is_empty

purge
